Filed Jan. 30, 1941 2 Sheets-Sheet 2 Patented July 25,- 1944 FISHING- REEL Richard P.` McMahon, Bronson, Mich., assignor to Bronson Reel Company, Bronson, Mich., a

corporation of Michigan Application January so, 1941,'sena1N0. 376,610 s claims. (c1. 24eusi My invention relates to fishing reels of the type commonly referred to as salt water reels. and in which the crank used by the angler to reel in is restrained from motion in the direction of reeling out, and the paying out of line must take place without rotation of the crank, either by disconnecting the spool from the crank or by permitting slippage of a friction connection between the two. Many reels of this type include means for permitting the line to be paid out in either of these ways. My invention includes among its objects and advantages a material increase in quietness and a material reduction in wear in the operation of such a reel.

In the accompanying drawings:

Figure 1 is a median section through a portion of a reel of the type referred to, indicating the application thereto of mechanism according to the invention;

Figure 5 is a fragmentary view indicating a modified construction in section as in Figure l;

Figure 6 is a similar fragmentary section indicating another modification; and

Figure 7 is a view in section on line 1-1 of Figure 6. i

In the embodiment of the invention selected for illustration in Figures l to 4, inclusive, the reel comprises the usual head plate I0 and tail plate l2 interconnected by pillars I4 and supporting the rotating spool Il.

The crank i8 has an operating handle 20 and is rotatable about the axis of the tubular crankshaft 22, which is pivoted on the stud 24. Integrally united to turn with the crankshaft 22 is the ratchet wheel 26 which may be restrained from rotation in the direction of reeling out by the pivoted pawl 28. Loose on the shaft 22 is the drive gear 30 which is at all times in mesh with the pinion I2.

I have illustrated an adjustable friction drive connection between the crankshaft 22 and the gear 30. The web of the gear 30 is positioned between friction washers Il and 26, and the friction washer 34 bears against the land 39 on the ratchet wheel 26, and the friction washer bears 'against a metallic washer 40, the central opening of which is flattened on opposite sides to engage the flattened sides 42 of the crank shaft 22. Above the washer 40 is a spring washer 44 v and above the spring washer is a thrust sleeve 48.

Ihe sleeve 46 lits over the non-circular outer surface of the shaft 22, as indicated in Figure 2, and is thus axially slidable .but not rotatable on the shaft. The star wheel 4l engages the threads I0 on thecrankshaft 22 and may be screwed down against the thrust sleeve Il to compress the spring washer M so that the web of the gear 3l isss gripped between the friction washers 3l and The crank Il abuts a shoulder at M on the crankshaft 22 and is fastened in place by the usual holding nut 56.

In the type of reel selected for illustration, means are also provided for disconnecting the spool entirely from the gear 30. The pinion 32 includes clutch teeth entering inside the female clutch member 51. The shifting yoke 50 has a U-shaped portion 6l)K the inner edge of which enters a groove in the pinion 32, and the outer ends of the yoke slide on posts I2 and are urged in the direction for engaging the clutch by coil springs 6I. The shifting plate 8B is bifurcated at its lower end to define arms 68 which extend across under the ends of the yoke 5l, and from the arms lugs 10 project diagonally upward. It will be apparent that movement of the shifting plate downward from the position of Figure 2 will carry the lugs 1I under the arms of the shifting yoke 58 and force the yoke and pinion out of clutching engagement with the spool, The shifting plate it is itself biased toward the position of Figure 2 by coil springs 12 pressing against the arms 14 of the upper corners of the shifting plate, and the movement of the shifting plate is guided by engagement of the lower arms 88 between the posts B2 and by engagement of the edges of the intermediate throat I6 with guiding posts 18. Means are provided for actuating the shifting plate in the nature of a shaft I0 journaled in the head plate i0, which shaft carries an eccentric pin 83 at its inner end, which pin enters a suitable slot 84 in the upper end of the shifting plate. The shaft carries an operating lever 82 provided with a handle 85 accessible to the operator.

'I'he parts so far described were known in the art prior to my invention, but in the reels of the prior art the pawl 28 was provided with a spring which constantly urged it into engagement with the adjacent teeth t6 of the ratchet wheel 28. Accordingly, during reeling in, the pawl would bounce from one tooth to the next and make a clicking or whirring sound depending on the speed of rotation. While such a noise is quite vthe ratchet wheel 26 is provided with a land I2,

the edge of which is provided with a circumferential groove to receive the pawl-biasing element Il. This element includes an arcuate spring porsaid crank to said spool including means permitting said spool to payout line without rotation vof l said crank; means for preventing rotation of said crank in the direction of paying out line, comprising: a toothed ratchet integrally connected to turn with said crank; a pawl pivoted on said 'l frame; and pawl-biasing means for engaging said pawl with said ratchet at the beginning of any rotation of said crank in the direction of paying out line', and continuously holding said pawl clearof the path of said teeth during rotation of said crank in the direction of reeling in: said 2. so that during movement of the ratchet in a clockwise direction. the force' of the frictionwill tend to relax or unwind the circular portion ll so far as its gripping action on the groove is concerned. whereas any initial movement of thev ratchet wheel in a counterclockwise direction will cause the portion It to grip the groove more strongly and to move the pawl 2t positively into the position of Figure2 at once. To prevent the pawl 2l and yoke ill from moving so far during reeling in that they become disengaged from each other, stop means are provided. I have illustrated a pin |02 positioned where it will strike the arm Il of the actuating element and limit the opening movement of the arm and pawl.

In the embodiment illustrated in Figure 5. the chassis plate i has no such countersink as at Il in the chassis plate Il, and the ratchet wheel i has a land i on its upper surface. which land. receives the holding element ||0 and also provides the friction surface for the adjacent washer 34.

Without further elaboration the foregoing will so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service. For instance. in

Figures 6 and 7 I have illustrated another em-` bodiment in which the ratchet wheel is adjacent the outer, covering portion of the end plate l0 instead of adjacent the chassis plate 88. In this embodiment, the ratchet wheel ||2 is splined on the shaft 22 by engaging the same flats 42 as the other splined elements, and the retaining spring IM is between the sprocket and the cover I0. In this embodiment the pin |02 is omitted, and the spring IM terminates in a finger Ill which projects down into the slot Ill in the pawl |20, which pawl is suitably pivoted on a pintle |22 fastened in the head plate Il. Upon counterclockwise rotation of the ratchet ||2, as viewed in Figure 7, the finger iii tends to move downward and to the left and the parts occupy the position of Figure "I, with further clockwise rotation of thev pawl prevented by the engagement of the pawl with the ratchet. Upon clockwise rotation of the ratchet ||2, the finger ile will move upward and to the right and the pawl ill will rotate counterclockwise to a DOsition entirely out of the path of the ratchet teeth. This movement is limited by engagement between ilnger IIS and the end of slot Ill. 'I'he thrust sleeve |24 transmits its thrust directly through the body of the ratchet wheelrdown to the overlying washer |20 which presses against the same spring washer M employed in Figure 1.
